Bug 246437 – sys-libs/glibc-2.7-r2 fails with linux-headers version (>=2.6.9), even when new enough linux-headers are installed

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Stian Skjelstad 2008-11-11 21:45:09 UTC]

This bugreport might be a bit bloat, but I still add it here, if others get stuck with the same fault (I'm poting the "fix" here aswell)

Symptom:

Calculating dependencies... done!

 * The die message:
 * linux-headers version too low!
 * 
 * If you need support, post the topmost build error, and the call stack if relevant.
 * A complete build log is located at '/var/tmp/portage/sys-libs/glibc-2.7-r2/temp/build.log'.
 * The ebuild environment file is located at '/var/tmp/portage/sys-libs/glibc-2.7-r2/temp/environment'.
 * 

Even thought sys-kernel/linux-headers-2.6.27-r2 is installed.

After some fidling and reading the ebuild sources, I traced down the problem. My CPP setting; due to bug #206240, is was set to

CPP="${CHOST}-gcc -E"

Setting it back to

CPP=${CHOST}-cpp

solves the issue.

Reproducible: Always

Steps to Reproduce:
1. emerge glibc-2.7 with CPP set to gcc -E

I think you've missed the fact that the bug you've mentioned
was closed as invalid, as in: 'self-harm'.
